Grade 3: Forces Causing Motion by Tracy Bellaire (eLesson Plan eBook)Bellaire,Tracy
Forces on an Object Support Force Thrust Force Drag Force Gravity Force All objects have a number of forces acting on them at any one time. The relative size and direction of the forces determine the motion of the object according to Newton’s first law Balanced forces – object stationary o...
NON-CONTACT FORCES C. Gravity: the force that pulls objects toward each other. Free fall: the motion of falling objects when the only force acting on it is gravity. Acceleration due to the force of gravity is 9.8 m/s/s. The size of the force depends on mass (matter, doesn’t change...

Net Force The combination of all forces acting on an object. If the forces are equal and opposite, then the net force is ZERO and there’s no motion. Force = 10 N Force = 10 N Balanced Forces Net Force = zero! Balanced forces produce no change in the motion of an object. (i.e....
